In response to requests from the EPA through the USGS, NASA flew AVIRIS on a De Havilland Twin Otter over lower Manhattan at mid-day on September
16 and 23, 2001. For these deployments, the Twin Otter was flown at altitudes of 6,500 and 12,500 feet.

The results of the USGS / EPA data collection from the AVIRIS are on the following site.

This web site describes the results of an interdisciplinary environmental characterization of the World Trade Center (WTC) area after September
11, 2001.

Information presented in this site was first made available to the World Trade Center emergency response teams on September 18, 2001 (Thermal hot spot
information), and September 27, 2001 (maps and compositional results).

The Airborne Visible / Infrared Imaging Spectrometer (AVIRIS), a hyperspectral remote sensing instrument, was flown by JPL/NASA over the World Trade
Center (WTC) area on September 16, 18, 22, and 23, 2001 ( Link to the AVIRIS JPL data facility).

The name says it all -
Airborne Visible / Infrared Imaging Spectrometer (AVIRIS)
They were using AVIRIS to map thermal hotspots for the benefit of ground level recovery/cleanup operations (where not to go).

Perhaps they do have some auxilliary radiation detectors in addition to the infrared scanners but there's little point in looking for ground level
radiation from an altitude of over 6000' unless you're flying downwind of Chernobyl just after the meltdown.

There had been quite a few crashes worldwide by 2001 involving planes with DU (B747, DC10, C130, L1011 are just some of them). The Tenerife crash of
2 747s in 1977 was probably the worst of them releasing a combined 3000kg of DU from the 2 planes so the idea of DU being exposed in a crash & fire
would be at the forefront of EPA thought at that time.

There is no mention of checking for radiation at all. Plus that is something the AVIRIS isnt even designed for. You can check that FACT at the AVIRIS
site at NASA yourself.

(note: The site you said verified it could search for radiation just stated it was one of the instruments used in the SCAR test. It did not say it was
used to detect radiation at all.)

No need to lie about what the AVIRIS can do, ULTIMA1. It can all be verified at the AVIRIS site itself at NASA at aviris.jpl.nasa.gov... .

AVIRIS Data

The AVIRIS sensor collects data that can be used for characterization of the Earth's surface and atmosphere from geometrically coherent
spectroradiometric measurements. This data can be applied to studies in the fields of oceanography, environmental science, snow hydrology, geology,
volcanology, soil and land management, atmospheric and aerosol studies, agriculture, and limnology. Applications under development include the
assessment and monitoring of environmental hazards such as toxic waste, oil spills, and land/air/water pollution. With proper calibration and
correction for atmospheric effects, the measurements can be converted to ground reflectance data which can then be used for quantitative
characterization of surface features.

...but the NASA site has no record of the USGS requesting them check for radiation. It isnt even in the results they found.
?

Maybe because the EPA asked for the flyover. Also i have posted the information about the EPA believing that DU from the planes was the cause of
radiation of the WTC. Which does not explain the radiation since we know that DU is not in the 757 and 767.

The source i posted also shows that the AVIRIS is able to do a lot more then imaging.

So the data provided by NASA. and all the output, is some coverup? It is all invalid then? It doesnt mention radiation on their results...shall I
provide the JPL NASA link again?

Also i have posted the information about the EPL believing that DU from the planes was the cause of radiation of the WTC. Which does not explain the
radiation since we know that DU is not in the 757 and 767.

All interesting stuff, but does not change the FACT that the AVIRIS was not used to detect radiation. You can bob and weave, but the FACTS keep
knocking you down for the count.

AVIRIS data collected on September 16, 2001, revealed a number of thermal hot spots in the region where the WTC buildings collapsed. Analysis of
the data indicated temperatures greater than 800oF in these hot spots (some over 1300oF) . Over 3 dozen hot spots of varying size and temperature were
present in the core zone of the WTC. By September 23, most of these fires that were observable from an aircraft had been eliminated or reduced in
intensity.

I have stated and shown that the EPA assumed radiation at the sites was casued by DU from the planes. But i have also proven that the planes supposed
to have been involved on 9/11 do not carry DU.

And we have proven that NASA did was not requested to use the AVIRIS to search for radiation, plus the AVIRIS was not designed to do that anyway!
Fnny how FACTS like that keep getting in the way of your conspiracy theory.
